MODELING THE EU'S EVERYTHING BUT ARMS INITIATIVE FOR THE LEAST DEVELOPED COUNTRIES

This study attempts to answer two key questions: what will be the likely impact of the EU's Everything But Arms (EBA) proposal, and, what would be the impact if the United States also were to implement a similar proposal? Using the GTAP model, the preliminary results in this paper show if only the EU's EBA proposal were implemented, then welfare in the least developed countries (LDCs) would increase by $2.5 billion (0.53 percent of their GDP), exports would grow by 3 percent, and GDP would grow by 2.3 percent. If the United States and the EU both implemented similar programs, then LDC welfare would increase by$3.1 billion (0.66 percent of GDP), exports would increase by 3.7 percent and total GDP growth by 2.9 percent. Another version of this scenario assumes that LDCs lack the supply capacity to exploit the new trade opportunities. In this case, LDC welfare increases by $0.9 billion (0.2 percent of GDP), exports grow by 4.1 percent, and GDP grows at 2.3 percent. The impact of this last scenario still may be overstated, given that trade preferences are not fully accounted for in the GTAP tariff database. Overall, the results suggest that improving market access for the LDCs could help raise per capita incomes above trend projections, but the gains are modest.Political Economy,

FOOD INSECURITY IN THE LEAST DEVELOPED COUNTRIES AND THE INTERNATIONAL RESPONSE

Despite adequate food supplies at the global level, many low-income countries experience food insecurity. Given that food deficits are projected to get even bigger in the future, the problem probably will only get worse. Added to the concern is the likelihood that global trade liberalization will increase prices and price volatility of major imported staple food commodities. Presently, the international safety nets that do exist are inadequate in stabilizing food supplies for the more vulnerable countries. Food aid has been the primary safety net, but is not sufficient to meet estimated needs around the world. The few alternatives to food aid that have been implemented so far have been either underutilized or ineffective. New safety net proposals could help stabilize grain import prices or manage import costs. This paper shows that 3 selected proposals (grain options, a revolving import compensation fund, and import insurance) would be much less costly than international food aid. The 3 programs would have cost about $300-$600 million per year, compared with the recent cost of food aid from all donors estimated at $2.9 billion. Each of the programs would be effective in stabilizing consumption variability. Improving the international safety net programs may help temper food security concerns and improve support in low-income countries for trade liberalization.Food Security and Poverty,

AN EXAMINATION OF ECONOMIC EFFICIENCY OF RUSSIAN CROP OUTPUT IN THE REFORM PERIOD

This paper examines economic efficiency of Russian corporate farms for 1995-98. Economic efficiency declined over the period, due to declines in both technical and allocative inefficiency. According to the average technical efficiency scores, Russian agricultural production could improve from 17 to 43 percent according to DEA and SFA analysis, respectively. The efficiency scores show that Russian agriculture presently uses relatively too much fertilizer and fuel and too little land and labor. Russian agriculture inherited machinery-intensive technology from the Soviet era, which may be inappropriate given the relative abundance of labor in the post-reform environment. Investment constraints have prevented the replacement of old machinery-intensive technology with labor intensive technology.Crop Production/Industries, Productivity Analysis,

AN OVERVIEW OF FACTORS AFFECTING THE SIZE OF LOCAL GOVERNMENT

This paper reviews many factors affecting the size of local government. These factors include: current demographic trends and changes in alternative service delivery arrangements, theoretical schools of thought, evidence on economies of size, whether current local governments are managed efficiently, and legal and political factors.Public Economics,

THE EXPORT MARKET FOR DIFFERENTIATED PROCESSED AGRICULTURAL PRODUCTS: THE ROLE OF FACTOR PRICES AND FIXED COSTS

The theories of monopolistic competition and ¡°love for variety¡± contend that the differences in firms¡¯ prices and market shares arise from product differentiation, which is linked to firms¡¯ fixed costs. This paper reviews these theories and their implications for prices and market shares of firms from developing countries seeking to expand their exports of processed agricultural goods. The study proposes a model showing the role of the firms¡¯ costs as a source of product differentiation. Using econometric methods, the model estimates the firms¡¯ residual demand elasticities, which indicate the degree of product differentiation and market power. The model also determines the effects of the firms¡¯ own costs and competitors¡¯ costs on the residual demand and market shares. Case studies for cocoa products and roasted coffee in the U.S. import market are examined. Exporters to the U.S. include developing countries that produce the raw cocoa and coffee. The results show that high prices and large market shares are associated with high levels of product differentiation in these markets. Also, market shares increase with the level of fixed costs, which are measured by proxy as advertising expenditures. The implication for small firms in developing countries is that increasing the degree of product differentiation through increased investment in advertising or research and development could increase their market shares and their export revenues.International Relations/Trade,

KELT-3b: A Hot Jupiter Transiting a V=9.8 Late-F Star

We report the discovery of KELT-3b, a moderately inflated transiting hot Jupiter with a mass of 1.477 (-0.067, +0.066) M_J, and radius of 1.345 +/- 0.072 R_J, with an orbital period of 2.7033904 +/- 0.000010 days. The host star, KELT-3, is a V=9.8 late F star with M_* = 1.278 (-0.061, +0.063) M_sun, R_* = 1.472 (-0.067, +0.065) R_sun, T_eff = 6306 (-49, +50) K, log(g) = 4.209 (-0.031, +0.033), and [Fe/H] = 0.044 (-0.082, +0.080), and has a likely proper motion companion. KELT-3b is the third transiting exoplanet discovered by the KELT survey, and is orbiting one of the 20 brightest known transiting planet host stars, making it a promising candidate for detailed characterization studies. Although we infer that KELT-3 is significantly evolved, a preliminary analysis of the stellar and orbital evolution of the system suggests that the planet has likely always received a level of incident flux above the empirically-identified threshold for radius inflation suggested by Demory & Seager (2011).Comment: 12 pages, 12 figures, accepted to Ap

KELT-1b: A Strongly Irradiated, Highly Inflated, Short Period, 27 Jupiter-mass Companion Transiting a mid-F Star

We present the discovery of KELT-1b, the first transiting low-mass companion from the wide-field Kilodegree Extremely Little Telescope-North (KELT-North) survey. The V=10.7 primary is a mildly evolved, solar-metallicity, mid-F star. The companion is a low-mass brown dwarf or super-massive planet with mass of 27.23+/-0.50 MJ and radius of 1.110+0.037-0.024 RJ, on a very short period (P=1.21750007) circular orbit. KELT-1b receives a large amount of stellar insolation, with an equilibrium temperature assuming zero albedo and perfect redistribution of 2422 K. Upper limits on the secondary eclipse depth indicate that either the companion must have a non-zero albedo, or it must experience some energy redistribution. Comparison with standard evolutionary models for brown dwarfs suggests that the radius of KELT-1b is significantly inflated. Adaptive optics imaging reveals a candidate stellar companion to KELT-1, which is consistent with an M dwarf if bound. The projected spin-orbit alignment angle is consistent with zero stellar obliquity, and the vsini of the primary is consistent with tidal synchronization. Given the extreme parameters of the KELT-1 system, we expect it to provide an important testbed for theories of the emplacement and evolution of short-period companions, and theories of tidal dissipation and irradiated brown dwarf atmospheres.Comment: 30 pages, 19 figures.

KELT-2Ab: A Hot Jupiter Transiting the Bright (V=8.77) Primary Star of a Binary System

We report the discovery of KELT-2Ab, a hot Jupiter transiting the bright (V=8.77) primary star of the HD 42176 binary system. The host is a slightly evolved late F-star likely in the very short-lived "blue-hook" stage of evolution, with \teff=6148\pm48{\rm K}, $\log{g}=4.030_{-0.026}^{+0.015}$ and \feh=0.034\pm0.78. The inferred stellar mass is $M_*=1.314_{-0.060}^{+0.063}$\msun\ and the star has a relatively large radius of $R_*=1.836_{-0.046}^{+0.066}$\rsun. The planet is a typical hot Jupiter with period $4.11379\pm0.00001$ days and a mass of $M_P=1.524\pm0.088$\mj\ and radius of $R_P=1.290_{-0.050}^{+0.064}$\rj. This is mildly inflated as compared to models of irradiated giant planets at the $\sim$4 Gyr age of the system. KELT-2A is the third brightest star with a transiting planet identified by ground-based transit surveys, and the ninth brightest star overall with a transiting planet. KELT-2Ab's mass and radius are unique among the subset of planets with $V<9$ host stars, and therefore increases the diversity of bright benchmark systems. We also measure the relative motion of KELT-2A and -2B over a baseline of 38 years, robustly demonstrating for the first time that the stars are bound. This allows us to infer that KELT-2B is an early K-dwarf. We hypothesize that through the eccentric Kozai mechanism KELT-2B may have emplaced KELT-2Ab in its current orbit. This scenario is potentially testable with Rossiter-McLaughlin measurements, which should have an amplitude of $\sim$44 m s$^{-1}$.Comment: 9 pages, 2 tables, 4 figures.
